consensus mechanism, helping the blockchain become energy efficient and secure. However, mining data reveals Ethereum’s heavy reliance on Flashbots — a single server — for building blocks, raising concerns over a single point of failure for the ecosystem.
Flashbots is a centralized entity dedicated to transparent and efficient Maximal Extractable Value extraction, which acts as a relay for delivering Ethereum blocks. from mevboost.org show that there are six active relays currently delivering at least one block in Ethereum, namely Flashbots, BloXroute Max Profit, BloXroute Ethical, BloXroute Regulated, Blocknative and Eden.As shown above, out of the lot, 82.77% of all relay blocks have been found to be built by Flashbots alone — contributing heavily to Ethereum centralization.
